If you ask me when my path in research truly began, I cannot answer with precision. There was no single, exact moment, no one day that marked a conscious and definitive choice. It was rather a quiet calling, a slow unfolding, driven by an inner need: the need to understand the world, to structure it, to make it more coherent and freer, at least in my own mind.

In Romania of the 1970s, in a modest, limited, and often rigid technological landscape, I discovered for the first time the secret fascination of computers. It was not only their astonishing power to execute commands that attracted me, but the possibility — still vague, yet deeply seductive — of creating living structures within them, worlds of their own, ordered by rules more rigorous than those of immediate reality.

I began my career with this simple and profound desire: to build constructs that would not be prisoners of machines, just as human beings should not be prisoners of the circumstances into which destiny or ignorance has pushed them.

My attempts to master as fully as possible the complexity of software and to infuse reasoning into inanimate systems were not, for me, merely professional stages. They were forms of the same quest: the search for a deeper freedom, the search for an order hidden in chaos, the search for an intelligence meant to serve life, not replace it.

This journey, spanning more than five decades, has borne many names: portability, software engineering, artificial intelligence, medical informatics, digital ecosystems, or digital twins.

But beyond labels and transient technologies, it has always been the same journey: the journey toward a world in which thought, life, and technology may coexist in harmony.

I write these lines now, looking back over this journey, not as a cold balance sheet, but as a living story that does not end with me. A story about what I sought, what I understood, and above all about what I became in the course of my search.

My research activity extended over several decades and covered different areas of computer science, from theoretical foundations to interdisciplinary applications. This section is organized by research domains and follows the evolution of ideas, methods, and results independently of the biographical framework in which they emerged.

The purpose of this presentation is to offer a coherent view of the themes addressed, the contributions made, and the links among them, without entering here into memoir-like detail. The personal and institutional context is treated separately in the Memoirs section.

Domains

• Foundations of Computer Science
• Software Engineering
• Artificial Intelligence
• Medical Informatics

The Research section presents my activity by domain and conceptual axis. The corresponding section in the Memoirs, by contrast, follows the same path chronologically, as the story of my formation, projects, people, and the contexts in which the ideas emerged.

Cross-cutting resources

• Projects
• Selected papers (dedicated pages)
• Selected published books (dedicated pages)

Alternative navigation: chronology (narrative)

For the biographical and institutional context of my research (years, episodes, people, laboratories), see the memoir section devoted to this path.
